email forwarding issue

first of all i would like to thank the developers of this software, for the good job they have done.

I have one issue with email forwarding. Let's say that i have a domain mydomain.com . I created one email account [email protected] and a second one [email protected] . The problem is that when i set [email protected] to forward the emails to [email protected] it does not do it . If i set it to forward to an email account not hosted at the same server it does it with no problem...

Actually unfortunately, i did not check the log file. I deleted the second account and tried to add an alias to the first, so i entered at the appropriate field the value with no @ bit. I tried to save it but it would not save this setting. I thought that it could be , because i had set this account as catch all. So now i have only one account. The strange thing though is that today i could not access my web pages. The owner of the folder www.mydomain.com was changed to something else than apache. Is it because i set this email account as admin ?
